I agree that the Infinity was most likely designed for the HIDs. The Saab, however, Im not sure about. From the same model year and up (2005), all the HID Saabs I see are projectors, so I dont know that you could get them from the factory in the reflector housing. This housing does have the cleanest cutoff Ive ever seen for a reflector, regardless of its intended use.
In any case, I just posted that because I was getting the impression that it seemed as though HIDs must be in projectors, and nothing else. Just clearing that up. . . . continue!
